Self-assembled ZnO 3D flowerlike nanostructures

3D flowerlike ZnO nanostructures were synthesized by a simple hydrothermal process. X-ray powder diffraction, scanning electron microscopy and transmission electron microscopy were used to characterize its structure and formation process. The relationship between the experimental conditions and the 3D nanostructures was discussed and the possible growth mechanism was also discussed based on the experimental results.
